The inventor of this new chip was thinking out of the box (he's a
physicist, not an engineer, so maybe that explains it)... He's also no

I used the words filters and color separates in an earlier post, but
that's probably not the best use of terms.

I don't think you'll ever see Foveon in a price war!
The cost of CCDs is largely due to the cost of production, not huge profit
margins.
I haven't heard of any revolutions in silicon economics around the corner, so
price improvement should be more steady than revolutionary.

Are you referring to the interpolation used to process the Bayer pattern

Hi Art,
Well, it's good to see that kind of honesty coming from you!
When you parrot something, you're obviously not making it up...it's the same
